I just couldn't help but to comment on such uniquely wrong and wrongly stated conclusions that would only serve to only tarnish the reputation of all other race realists, should they become de-facto points of speech for those discussing the issue.<br /><br />Learn how to dissect an issue in a rhetorically valid and analytically competent manner before you post in public about it. You'll save yourself, and those that may associate with you, a lot of embarrassment.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-227780861638767023.post-19419399145769525922008-06-21T19:29:00.000+01:002008-06-21T19:29:00.000+01:00I cite three studies--the three most recent studie...I cite three studies--the three most recent studies on the topic indexed in PubMed. All come to the same conclusion: no significant different in mean fundamental vocal frequency between black and white men. Rushton relies on a single, older study to argue the opposite.<BR/><BR/>You are clearly not very perceptive. <BR/><BR/>I said <A HREF="http://youtube.com/results?search_query=chris+tucker&search_type=&aq=0&oq=chris+tuck" REL="nofollow">Chris Tucker</A>, not Chris Rock.<BR/><BR/>The point is, you're obviously not relying on fundamental frequency to judge speakers' race. Even if there were a difference in mean fundamental frequency, it's inconceivable it would be of the magnitude necessary to use it to reliably make such determinations.<BR/><BR/>I didn't say anything about a "widespread perception". I said it is "often claimed"--usually by the same types who think black men are taller than white men--despite voluminous evidence showing the opposite is true. No one who has interacted with actual blacks (as opposed to watching too much television) is likely to hold either belief. (With the possible exception of certain "ethnic" whites, who could conceivably be shorter on average than American blacks.)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-227780861638767023.post-46268766839356761332008-06-21T15:04:00.000+01:002008-06-21T15:04:00.000+01:00One study - which admits to disputing the findings...One study - which admits to disputing the findings of an earlier study does not overturn what you say at Sailer's site is widespread perception. <BR/><BR/>You say all our ears are lying, but you also mention Chris Rock: now, <I>why</I> is Chris Rock's voice so notable...?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-227780861638767023.post-15926018803264294452008-06-20T22:09:00.000+01:002008-06-20T22:09:00.000+01:00I can usually tell when a negro has entered the sc...<I>I can usually tell when a negro has entered the scene on TV without looking at the screen... and it's depth of voice.</I><BR/><BR/>Yeah, I guess that's why it's so easy to mistake Chris Tucker for a white man.<BR/><BR/>Typical black and white voices are easily distinguished, but this has nothing to do with fundamental frequency. Blacks have poorer quality, "noisier" voices, not deeper voices:<BR/><BR/>J Speech Hear Res. 1994 Aug;37(4):738-45.<BR/><BR/> Speaker race identification from acoustic cues in the vocal signal.<BR/><BR/> Walton JH, Orlikoff RF.<BR/><BR/> Department of Communicative Disorders, University of Mississippi, University 38677.<BR/><BR/> One-second acoustic samples were extracted from the mid-portion of sustained /a/ vowels produced by 50 black and 50 white adult males. Each vowel sample from a black subject was randomly paired with a sample from a white subject. From the tape-recorded samples alone, both expert and naive listeners could determine the race of the speaker with 60% accuracy. The accuracy of race identification was independent of the listener's own race, sex, or listening experience. An acoustic analysis of the samples revealed that, although within ranges reported by previous studies of normal voices, the <B>black speakers had greater frequency perturbation, significantly greater amplitude perturbation, and a significantly lower harmonics-to-noise ratio than did the white speakers</B>. The <B>listeners were most successful in distinguishing voice pairs when the differences in vocal perturbation and additive noise were greatest</B> and were least successful when such differences were minimal or absent. Because there were <B>no significant differences in the mean fundamental frequency</B> or formant structure of the voice samples, it is likely that the listeners relied on differences in spectral noise to discriminate the black and white speakers.<BR/><BR/> PMID: 7967558 [PubMed - indexed for MEDLINE]Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-227780861638767023.post-51596313641835094452008-06-20T20:45:00.000+01:002008-06-20T20:45:00.000+01:00Don't believe it.I can usually tell when a negro h...Don't believe it.<BR/><BR/>I can usually tell when a negro has entered the scene on TV without looking at the screen... and it's depth of voice.Anonymousnoreply@blogger.com
